« Technical analysis of the BLUE SEA 250A through-hull connector »

The BLUE SEA 2201-BSS through-hull connector is a critical component for the safety and efficiency of marine electrical installations. Its primary function is to create isolated and robust cable passage points for high-current cables, typically between the engine compartment and the electrical panel, or to power energy-intensive equipment through a technical bulkhead. It transforms a simple drilled hole into a secure electrical interface, preventing cable sheath abrasion on sharp edges and reducing the risks of short circuits or water ingress.

In terms of installation scenarios, it is ideal for battery cable, alternator, or inverter/charger cable passages. Its reinforced thermoplastic body and tinned copper studs enhance the longevity of the connection in saltwater and humid environments. The IP66 rating is a key indicator of its ability to withstand marine conditions, setting it apart from non-marine industrial solutions. It is critical to properly tighten the serrated flange nut to ensure a low-resistance connection and prevent overheating.

While versatile, this connector is specifically sized for 5/16"-18 studs and high currents. It is not the optimal choice for low-diameter signal cable passages or applications requiring multiple connections in a confined space. For these cases, other solutions such as terminal blocks or cable glands would be more appropriate. Its role is to provide a solid and isolated junction point for a pair of power cables.

How is the 2201-BSS connector mounted on a bulkhead?

The connector is flush-mounted through a cutout in the bulkhead. It is then secured using screws through the two mounting holes on its front face.

What type and size of screw are required to mount the connector?

Mounting holes are designed for #10 screws (US standard) or M5 screws (metric standard).

What is the distance between the mounting hole centers?

The distance between the centers of the two mounting holes is 0.87 inches (22.2 mm).

Should a gasket or sealant be used during installation?

Yes, the mounting face of the connector is designed to allow the use of a gasket or sealant (sealing compound) to ensure a fully watertight installation and maintain IP66 classification.

How to install the BLUE SEA 2201-BSS through-hull connector and ensure its watertightness?

The BLUE SEA 2201-BSS through-hull connector is designed for installation through bulkheads, decks, or hulls. It features two 5/16"-18 UNC threaded studs for electrical connections. For mounting, it has two clearance holes for #10 or M5 screws.

To ensure watertightness, this connector has an IP66 environmental rating, meaning it is protected against dust and powerful water jets. It is recommended to use a suitable gasket or sealant on the mounting surface during installation to provide maximum water protection.

What are the electrical specifications (current and voltage) of the BLUE SEA 2201-BSS through-hull connector?

The BLUE SEA 2201-BSS through-hull connector is designed to handle high-intensity electrical systems. It can support a continuous current of up to 250 amperes (A) and a maximum voltage of 48 volts direct current (VDC).

The 5/16"-18 studs are made of tinned copper alloy, ensuring excellent electrical conductivity and increased resistance to corrosion, which is essential for demanding marine environments.
